Applications of generalized Ruscheweyh derivative to univalent functions with finitely many coefficients

By making use of the generalized Ruscheweyh derivative, theauthors investigate several interesting properties of certain subclasses of univalent functions having the form f(z) = z - Σn=2..m ((1 - β) en) / ((1 - nβ + α(1-n)) B1λ, μ(n)) zn - Σk=m+1..∞ akzk.
